MACHINERY. FOR THE MANUFACTURE OF INLAID LINOLEUM.

SJEEGIFICATION forming part of Letters Patent N 0. 697,551, dated April15, 1902. Application filed May 1, 1901. Serial No. 58,281. (No modeL)To aZZ whom, it may concern:

Be it known that I, CHARLES HERBERT SCOTT, a subject of the King ofGreat Britain and Ireland, residing at Gloucester, in the county ofGloucester, England, have invented Improvements in the Manufacture ofInlaid Linoleum and in Machinery or Apparatus Therefor, of which thefollowing is a specification.

This invention relates to the manufacture of inlaid linoleum,particularly that of the kind in which the pattern or design consists ofsmall figures-for instance, squares of different colors and arranged soas to produce the required effectand to machinery or apparatus for usein such manufacture.

According to this invention a mixture of loose granulated linoleum iscompressed during passage through a die into pieces of the required sizeand shape, which pieces as they are discharged from the die are pressedonto a canvas or other backing, and for the purpose of enabling a greatvariety of patterns or designs to be produced at small expense theaction of devices designed to efiect the distribution from thesupply-hoppers of the granulated linoleum of which the pattern is to beformed is regulated or controlled by pin or tap'pet drums, bands, or thelike, or by drums, bands, or the like formed with perforations or slots,the pins or tappets or the like or the perforations or slots or the likebeing arranged or disposed according to the pattern or design to beproduced, the drums, bands, or the like being capable of being changedor shifted when it is desired to alter the pattern or design produced,and the arrangement being such that only such material as is requiredfor forming the pattern or design will be distributed from thesupplyhoppers.

Machinery or apparatus according to this invention may be variouslymodified.

The accompanying-"drawings illustrate, by way of example, onearrangement of machine, Figure 1 being a longitudinal section, Fig. 2 anend view of the lower part of same, and Figs. 3, 4, and 5 are detailviews hereinafter referred to. I

In the frame 1 of the machine are mounted a pair of shafts 2 2, eachcarryinga drum 3.

' Around these drums passes an endless band 4, that serves to supportthe canvas backing 5, onto which the pieces of linoleum are pressed. Theshaft 2 has fixed to it a ratchetwheel 6, which has a step-by-stepmotion imparted to it by a pawl 7, which is carried by an arm 8, turningabout the shaft 2 and linked to a lever 9, carrying an abutment orroller 10,

' The upper part of each die-plate 13 is formed with a number of groovesor channels 14, which are of slightlyless width than the squares orother figures in the pattern and may conveniently be horizontal. Aboveeach die-plate is a hopper 15, adapted to contain granulated linoleumand to deliver the same to the several grooves or channels in thedieplate at or about the middle of their length. The grooves are towardone end covered by a heated plate 16. The plate may be made with apassage 16, through which steam or hot air is passed or in whichgasburners may be arranged. Each groove or channel 14; is fitted with aplunger 17, retained in position by a cover-plate 18, common to the setof grooves.

' In connection with each die-plate 13 a trans verse bar. 19 is arrangedso as to be capable of a parallel to-and-fro movement along the frame ofthe machine. The movement of this bar may conveniently be obtained byconnecting it by links 20 to a lever or levers 21, which is or areoscillated by a cam or cams 22 on the main shaft 12. The front edge ofthe bar 19 extends beneath the projecting ends of the plungers 17, eachof which is formed with a downwardly-extendinglug or hook 17 adapted toengage with a shallow flange or lip 19, formed along the front of thetransverse bar, the arrangement being such that during the backwardmovement of the bar 19 any plunger engaged by such lip will be drawnback therewith. The rear portion 19 of said bar is extend ed upwardlyand carries or has pivoted or hinged to it a series of abutmentpieces23, one of which is opposite to each plunger. When these abutment-piecesare in their operative positions and the transverse bar 19 is moved toand fro, their respective plungers will also be moved to and fro andwill at each inward stroke discharge from the grooves orchannels 14certain quantitles of linoleum mixture, while at each outward strokefresh supplies of mixture will drop from the hoppers 15 into the groovesor channels 14. When the abutment-pieces 23 are raised into theirinoperative positions, the plungers will be left at the ends of theiroutward strokes and no mixture will be discharged from their grooves.

For the purpose of bringing the several abutment-pieces 23 into orkeeping them out of action during the forward stroke of the transverseabutment-bar 19 in the order necessary for the production of therequired pattern or design each abutment-piece 23 is connected, by meansof a link or rod 24, to one end of a lever 25, the other end of whichhas a metal pin or point 26 working againsta pattern-drum 27, formed ofor covered with sheet metal or other substance having perforations,slots, or holes 28, Fig. 5, punched through it. This drum has anintermittent rotary motion imparted to it from the main or cam shaft 12of the machine at those periods when the transverse abutment-bar19 is atrest in its rear position. In the example illustrated it is shown drivenby belt-gearing from the shaft 2. Just before the drum is moved akickerbar 29, extending across beneath all the levers 25, actuates themin such wise as to free their points 26 from the perforations, slots, orholes 28in the pattern-drum, the kickerbar 29 again moving after thedrum has moved so as to allow the points 26 of the respective levers torest on the surface of the pattern-drum and so hold their abutmentpiecesout of action or to enter the perforation, holes, or slots and allowtheir abutmentpieces to come into action, according to the pattern to beproduced. Across the front end of the grooves there is formed throughthe die-plate 13 a slot 30, which serves as a delivery, whence thelinoleum mixture discharged from the grooves or channels 14 is depositedonto the canvas backing 5, passing beneath it. \Vithin this slot isfitted a pressure plate or plates 31, which is or are reciprocatedvertically by means of bell-crank le vers 32, to which it or they is orare connected and which are linked to a lever 33, oscillated by a cam orcams on the main or cam shaft 12. The pressure plate or plates is or arearranged and actuated so that during a portion of the forward stroke ofthe abutment-bar 19 they close the outlet ends of the grooves orchannels 14, is or are then raised, so as to allow of the mixture beingdischarged from the said grooves or channels into the deliveryslot 30,and is or are then moved down again, so as to force out the mixture ontothe canvas backingbeneath. The delivery-slot may be continuous for thewhole width of the machine; but it can be divided into vertical grooves,the number of which corresponds to or is a multiple of the number ofgrooves or channels 11 in the die-plate. The thickness or width of thedelivery-slot and pressure plate or plates is slightly less than thelength of the squares or other figures forming the pattern.

Each supply -hopper is provided with a shaking-bar 34,with arms 35,adapted to shake the loose granulated linoleum into the grooves orchannels in the die-plates.

The action of the machine is as follows: Assuming that all the plungers17 are in their outermost positions, the action of the shakers 35 causesthe horizontal grooves or channels 14 in the die-plate to be chargedwith granulated linoleum. The abutment-bar 19 now travels forward andwith it such of the plungers 17 as have their abutment-pieces 23 in theoperative orlower position, which plungers compress the linoleum intothose portions of the grooves or channels 1 1 in the die-plate which arebeneath the heated plate 16, the pressure plate or plates 31 preventingfor the time being the discharge of the linoleum from said grooves orchannels. The forward movement of the abutment-bar 19 then ceases andthe pressure plate or plates 31 is orare lifted, leaving the ends of thegrooves or channels 14 open, whereupon the abutment-bar advances,pushing the compressed linoleum out of the grooves into thedelivery-slot 30 and beneath the pressure plate or plates, which thendescends or descend rapidly and pushes or push the compressed pieces oflinoleum out of the delivery-slot onto the canvas backing 5 below. Theabutment-bar 19 then travels back, the flange or lip 19 along its frontedge engaging with and drawing back the plungers 17 to their originalposition, the kicker-bar 29 lifts all the points 26 clear of thepatterndrum 27, whereupon the pattern -drum is partly rotated, so as topresent a fresh row or series of perforations, holes, orslots 28 to thelevers. This operation is repeated, the canvas backing 5 moving forwardstep by step and the plungers 17, which are moved forward at eachforward stroke of the abutmentbar 19, being varied in accordance withthe varied disposition of the perforations, holes, or slots in that partof the drum which is for the time presented to the abutment-levers.Whenever a perforation, hole, or slot 28 in the drum 27 comes oppositethe point 26 of the lever 25 of a given abutment-piece 23, thatparticular piece will drop into its operative position and thecorresponding plunger 17 will travel forward and push a compressed pieceof linoleum under the pressure-plate 31, which deposits it onto thecanvas backing.

The patterns can be changed by changing the perforated sheet-metalcovering of the drum or by changing the drum itself.

The canvas backing may, in some cases, be

5 forth. 2. In apparatus for the manufacture of incaused totravelcontinuonsly at such a speed 5 traveling in a horizontal,vertical, or other convenient direction can be used. Also the drums,sheets, or the like may be provided with pins, knobs, or tappets adaptedto bring the plungers into action or hold them out of action.

As will be understood, there may be any desired number of grooved orchanneled dieplates with appurtenances, each being pro' vided with ahopper for containing a different-colored linoleum, the number orvariety of patterns or designs which the machine can produce varyingaccordingly. The several die-plates are fixed one behind the other uponthe machine, and the several abutmentbars are connected together bylinks 36 and operated simultaneously.

In some cases some or each of the hoppers may be divided intocompartments, each of which can be charged with a different-coloredlinoleum.
